Joss Whedon’s 2013 Wesleyan commencement speech:
So here’s the thing about changing the world. It turns out that’s not even the question, because you don’t have a choice. You are going to change the world because that is actually what the world is.
You do not pass through this life, it passes through you. You experience it, you interpret it, you act, and then it is different. That happens constantly. You are changing the world. You always have been.
And now it becomes real on a level that it hasn’t been before.
